COM POSITE RAILWAY-TIE.

sPEcIFiCATIoN forming part of Letters Patent No. 670,495, dated Maren 2e, 1901.

Application iiled December 18, 1900. Serial No. 40,278. tNo model.)

To a/ZZ whom it may concern.-

Beit known that I, CHARLES COPPAGE HAR- RELL, a citizen of the United States, residing at Bainbridge, in the county of Decatur, State of Georgia, have invented a certain new and useful Improvement in Composite Railway- Ties, of which the following is a specification, reference beinghad to the accompanying drawings.

This invention relates to railway-ties of that class shown in my allowed application, Serial No. 15,511, led May 4, 1900, and has for its object a tie in which practically all the nuts are dispensed with and in which the rails are fastened on their chairs or supports by resilient and readily-detachable securing means.

With this and other objects in View my present invention consists of the peculiar construction, arrangelnent, and combinations of parts, as hereinafter described, and then definitely claimed at the end hereof.

In the drawings accompanying and forming part of this application, which represent the preferable, though not necessary, embodiment of my invention, Figure 1 is a longitudinal vertical section. Fig. 2 is a perspective View of one end of the framework with a chair and rail thereon, but without the plastic covering. Fig. 3 is an enlarged sectional detail of one end, showing the method of securing the rail in place. Fig. 4 is a perspective view of the chair or support for the rails. Fig. 5 is a top plan, and Fig. 6 is a section through the line B B of Fig. 5.

Referring now to the details of the drawings by letters, a represents a preferably flat metallic base-plate, and at a suitable distance over this base are two parallel and longitudinal bars b c, which for the major part of their length are also parallel to the base o, and at their ends are bent downwardly at an angle, so as to meet the base, as shown in Fig. Land to which base the said ends are rmly secured base are turned upwardly, as at et.

Preferably intermediate of the ends and between the bars b and c I secure a stilfeningbrace d, which is riveted to the base aand is provided with two upwardly and outwardly projecting arms d, whose ends are formed into eyes d2, and substantial rivets e rigidly se-V cure this brace in position by passing through theV said eyes d2 and through the bars b and c, and thus firmly secure the whole structure at these points. While I prefer to use rivets, it is evident that pins could be used; but these would not give as much satisfaction.

On top of the bars b and c are secured my rail' chairs or supports f, which are preferably malleable castings and of the novel form shown in Fig. 4 One of these chairs rests on top of the bars b and c at each end and has projecting downwardly therefrom between said'bars two integral posts or standards g g', whose ends are reduced and shouldered at g2 and firmly riveted to the base a. This rail chair or support is shown best in Figs. 3 and 4 and comprises a rm seat in the center, on which is placed a cushion of compressed ber or the like t of the peculiar shape shown in Fig. 4. On the sides of the ends of this chair are formed upwardly-projecting iianges f', and at the extreme ends are flanges Through each of the side flanges are formed twoA perfor-ations f3 f4, Whose purpose will be hereinafter described. The metallic framework as thus constructed is incased or embedded in cement, concrete, or analogous material h, except that this does not extend over the tops of the chairs or rail-supports, but merely extends up to the top of the end flanges f2 and is iiush with them at these points, thus leaving the tops of the chairs exposed, as shown in Fig. l.

I deem it important that the casing be made of the shape shown in top plan view in Fig. 5 and in vertical section in Fig. 6, inasmuch as by this construction the maximum load comes upon that part which is of maximum strength.

Assuming that the framework has been incased with its plastic covering or housing h, the rails are secured to them as follows: The cushion t' is placed in its seat, the rail is placed thereon, and a spring-clamp fastening k, of the peculiar shape shown in Fig. 3, has

one of its ends placed against one of the end anges f2. A spike or pin is then slipped through the upper perforations f3, and a pinch-bar or other suitable lever is forced between said spike and the spring, and the latter is forced down until it is entirelybelow the lower perforation, when a fastening-pin Z is passed through the lower perforations, which are so located as to support the pin Z in the proper position to firmly hold the spring in place. The pinch-bar and upper spike maynow be withdrawn and the other springfastening secured in place in a similar manner. The inner ends of these springs 7s are formed so as to fit into the recess fr in the cushion t', (sce Fig. 4,) as well as to firmly bear against the top and side of. the base of the rail.

From the foregoing and the accompanying drawings it will be seen that I have invented a composite railway-tie of such construction as to avoid the necessity of all nuts, which, as is well known, are impossible to be kept from shaking loose, one in which the rails are secured to their chairs or supports by a resilient fastening which is Very easily removed when necessary and in which the fastening is so simple that the rail can be easily released from the tie and the cushion of compressed Iiber or similar substance be readily replaced or renewed. It is also manifest that the tie and its plastic housing are so proportioned as to cause the greatest weight to be borne by the parts which are made the strongest, so as to best support the loads which they must bear.

It is obvious that many changes may be made in the construction of the tie without departing from my invention, and I intend the following claims to cover such modifications and variations as will naturally come within the scope of my invention.

What I claim as new isl. In a railway-tie, a framework comprising a base, an upper bar substantially parallel with said base for the major part of its length and adapted to support rails; the said upper bar beingformed with ends extending downwardly atan oblique angle and secured to the base; and an intermediate brace secured to the upper and lower bars; substantially as described.

2. In a railway-tie, aframework comprising a base,a pairof vertically-disposed upper bars substantially parallel with each other and with the base for the major part of their lengths; the said upper bars being formed with ends extending downwardly and at an angle and secured to said base, substantially as described.

5. In a railway-tie, a framework comprising a base, an upper bar substantially parallel therewith for the major part of its length and adapted to support rails; the said upper bar being formed with ends extending downwardly at an oblique angle and secured to said base; an intermediate brace secured to the upper and lower bars; and the framework being embedded in plastic material; substantially as described.
